RECOVERY OF COPPER FROM COPPER ORES

9-5-1972A method of recovering copper from finely divided oxidized copper ores wherein the improvement comprises: leaching oxidized copper ore present in a limestone gangue, that is ground to approximately -65 mesh particles size using a hot strong aqueous sodium hydroxide copper solvent solution in each of three steps of 10 to 30 minute time intervals

Copper Production: How Is Copper Made?

Virtually all sulfide-type copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by smelting. After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper

The concentrated ore must be converted into a form which is suitable for reduction. Usually the sulphide ore is converted to oxide before reduction. Oxides are easier to reduce (for the reason see box). Thus isolation of metals from concentrated ore involves two major steps viz., (a) conversion to oxide, and (b) reduction of the oxide to metal.

How Does Acid Affect Copper?

The green color on the statue now is not a result of acid rain, but of natural oxidation as a reaction of air and moisture. The statue could be cleaned in its entirety using a weak acid solution, but this would remove the protective copper oxide, wear away some of the copper and leave the copper underneath exposed to more oxidation.
